That is the best you can do unless you have a limitless budget.
Not quite, with fairly low DIY electrictronics skills you could have a raspberry pi based system triggering high brightness LED's strobing to disorientate coupled with a loud alarm, multiple sensors, camera & email all off ebay for not much at all, just need a day or two to fit. Would certainly scare the sh!t out of anyone and push the odds back in your favour.
